Answer: D
Step-by-step explanation:
(x-9)² = x-3
(x-9) (x-9)= x-3
x² - 9x-9x +81 = x-3
x² -18x+81 =x-3
x²-19x+84 =0
(x-12)(x-7)=0
x=12 or 7

Answer:
x= 0, and x=4
Step-by-step explanation:
x² -x = 3x, we can subtract 3x from both sides
x² -x -3x = 0, combine like terms
x² -4x = 0 , factor x
x *( x-4) = 0, if the product of 2 numbers equals 0 at least one is 0
x=0 and
x-4 = 0, add 4 to both sides
x= 4
Answer:
